capital and operating costs for a plant of 24 t/a capacity have been calculated (Table VI). Costing commences with the presentation of wet, impure gold sludge to the plant, and ends with molten, pure gold available for casting. In this estimate, a feed material with a gold-to-silver ratio of 9:1 and
The Pierina Gold/Silver Mine produced 152,000 ounces of silver last year at a cost of $852/ounce. This means that the once lowest cost gold mine in the world, has become one of the highest cost gold mines in the world. Major mining companies have operating gold mines with total cash cost of gold ranging from $500/ounce to $600/ounce in 2012.

As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide. The BIOX process destroys sulfide minerals and exposes the gold for subsequent cyanidation, thereby increasing the achievable gold recovery. Improves rates of gold recovery ; Reduces capital cost
capital and operating costs. Conversely, low-grade deposits must be treated at the lowest possible cost, even though this usually means sacing some gold recovery. The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is
There are currently two non-GAAP cost reporting measures employed by the gold mining industry. Cash cost is the cost to mine gold-bearing rocks, process the ore, and sell the gold. It factors in basic mining, processing, transport and refining costs but ignores sustaining capital, general and administrative (G&A) expenses, and other associated ...
